There are two versions of the HP49 emulator:

1-Yuser.exe	: Emulate the HP49 at its real speed
2-YUserfast.exe	: Emulate the HP49 as fast as possible (speed will depend on your PC)

WARNING: If you're using a slow PC (< Pentium 133) and depending on how many memory cache
your CPU have, YUser.exe may be slower than a real HP49.
In order to get your HP49 speed:
 * Press and hold the [ON] key then press [F4]
 * Release both keys
 * You should be in the "Tests" screen now
 * Press [2] to get the speed

A real HP49 runs at around 4MHz

Enjoy.
